GEORGE W. KUENNETH, OF EATERSON, NEW JERSEY, ASSIGNOR, -BY MESNE ASSIGN- MENTS, T0 JEANNETTE KTJENNETH, or PATERSON, NEW JERSEY.

WARPING-MACI-IINE.

State of New Jersey, have invented certain new and useful Improvements in Warping- Machines, of which the following is a specification. v V V This invention relates to warping machines and it consists in improvements designed to produce a better quality of prodnot, promote accuracy in the various calculations which the attendant is required to make and facilitate the entire warping operation. One part of my invention consists in novel means for obtaining relativemovement as between the reeds and warp in the direction of the length of the reed dents, whereby to prevent the warp threads wearing nicks in the reed dents. Another part of my invention consists in mounting the condensing reed so that it may occupy either I of two positions, one the working position and in proximity to the roller or equivalent guide over which the warp extends immediately before being wound on the reel and the other a retracted position to allow free access to the warp at the point where it is just about to be wound on the reed. Another part of my invention consists in novel means for obtaining traverse of the reed carriage when the machine is used forsection warping, and also for resetting the carriage manually to each positionfor laying on the reel a new section of warp. Another part of my invention consists in novel means whereby indication may be afforded as to when the end of a predetermined length of the warp has been wound on the reel, when lease cords should be introduced into the warp and (in section warping) how far back the reed carriage should move to dispose the same accurately in position to start the winding on of a new section of warp. My invention contains certain other novel features of more or less importance to be pointed out hereinafter.

a is the frame and b the reel of a horizontal warper; in the actual construction shown this warper has means for traversing the reed carriage transversely, that is, parallel with the axis of. the reel, allowing the warp to be laid on the reel in sections, spirally, making it therefore what is known as a Swiss horizontal warper. e

In the frame are arranged the usual fixed parallel guide rods'c and between them and preferably ,in the same horizontal plane is journaled the feed-screw cl The feed-screw is driven in the well-known manner from a sprocket-wheel (not shown) on the reel shaft by a chain 6 anda sprocketwheel 7 which, however, according to my invention is adapted tobe revoluble (see Fig; 1 1) on the feed-screw d between two collars 9 but may be made fast theretowhen the conical end it of a hand-screw i in the end of the feed screw isinwardly advanced,

by turning such hand-screw, and so through the medium of a wedge-piece 7' arranged in a slot 7c in the feed-screw {establishes a frictional interlock between the sprocketwheel f and feed-screw. The mechanism last described obviously constitutes a'clutch whereby when the reel is in motion the feedscrew will or will not be rotated according as the clutch is established or disestablished.

The body of the carriage (that is, the carriage proper) is a casting in the form of a simpl arch Z formed at one side with a pair of spaced bearings m to receive the rear guide-rod c and at the other side with an anti-friction roller a resting on the forward guide-rod, its two upright portions being connected by spaced webs 0 0 (Figs. 5 and 8), said webs being apertured to receive the feed-screw. There is a vertically movable nut p having a pair of stems g g '0, saidworm whose function will appear later, being mounted on the feed-screw and slidable thereon but splined therewith by having a feather t engaging in a spline a in the feed-screw. In th position shown in Fig. 8 the nut engages the feed-screw so that the carriage will move along the guiderods if the screw be turned; in this position the nut is held by a pin 41 mounted in the superstructure or arm (to be described) of the carriage and engaging in the upper one of two holes of the stem 9. By removing the pin the nut may be held elevated, clear of the screw, upon inserting the pin in the lower one of said holes, whereupon the carriage may be pushed by hand along the guideway, i. 6., without turning the feedscrew, I

The carriage proper has the depending bearing to in which is journaled a shaft carryin a worm-wheel y meshing with the worm 7* and a disk 2.

2 designates the aforesaid superstructure or arm of the carriage fixedly secured upon the body portion Z thereof. This arm is equipped at its rear end with the usual roller 3 over which the warp extends before being wound on the reel; also with an upstanding bracket 41 for the lease rods 5. In its free end it has a pair of vertical guideways 6 in which the downwardly projecting stems 7 of the reed carrier 8 (to which the main reed 9 is suitably clamped) are guided. In upstanding supports 10 onthe arm 2 is fulcrumed between its ends a lever 11 the outerend of which takes under and supports "the reed carrier 8 and the inner end of which has a link 12 connecting it with an eccentric point on the crank disk 2. At

inn'er end of the lever 11 is a pair of bosses 13 in which may slide the horizontal stems ll of the carrier 15 for the condensing reed 16, the bosses having aset-screw 17 to bind against one of the stems to hold the reed carrier in any position to which it is horizontally adjusted.

Here I may mention a noteworthy feature of my invention. In winding on the warp it is very desirable to have the condensing reed as close as possible to the reel b in order to secure accuracy of placement of the warp on the reel; on the other hand, the warper frequently requires clear access to the warp between the condensing reed and reel. In working position the parts are arranged as shown in Fig. 1, with the condensing reed at its inward limit with respect to the reed; but when the warper needs to have access between the reed and reel he releases the screw 17 and shifts the reed carrier outward in the bosses 13.

In view of the foregoing it will be obvious that so long as the worm 1' is rotated by the feed-screw the lever 11 will through the parts 1 w, 2 and 12 be oscillated, causing the reeds to move up and down with reference to the warp whereby the latter is prevented from cutting nicks in the reed dents.

In Swiss or section warping'the warp is wound, on the reel in sections of predeter- (by traversing the reed carriage) one after another, the winding on of each section being started with the reed carriage reset beyond the point of 1ts starting to traverse for the wlnding on of the preceding section a distance which is aimed to be (and in per first place, when the end of a section being wound is approaching; it is also desirable that he should have means to indicate when in the winding of a section the lease cords are to be introduced into the warp. It is also desirable that when he manually resets the carriage after winding on one section preparatory of the winding on of another he should have means to indicate accurately when the carriage has reached the proper new positionin other words has been reset the distance of its traverse plus the section width. best in Figs. 11 to 1 1.

18 is'a bracket secured to the near side of the frame a. in Fig. 1 and penetrated by the feed-screw (Z. Beneath the feed-screw and Such means are shown mined length and equal width each spirally iournaled in the bracket is a shaft 19 (Fig.

outer sidepinion 22, the gear, sprocket-wheel and pinion being all pinned or otherwise fixed to the shaft. A sprocket-chain 23 extends around the sprocket-wheel 21 and a sprocket-wheel 21 on the feed-screw. Meshing with the pinion 22 and journaled in the bracket 18 is a gear 24 having a handle 25 arm 26 set at a suitable incline so that a dial indices '0, 1,2, 3, etc.,' the intervals between 27 which is journaled thereon on astud 28 (being insulated from the stud by insulation 28, Fig. 14) will'be in Convenient position for reading. This dial has a scale, as seen in F ig.'13, provided at regular points with which I' find it convenient to mark off into sixteen equal subdivisions; at regular intervals corresponding with these subdivisions I provide holes29 in the dial .to receive metal pegs 30. The dial has peripheral worm teeth 31 meshing with a worm 32 journaled on but insulated (by insulation 33) from a stud 34, the worm being formed on a sleeve 35 equipped withthe pinion'36 which meshes with the gear 20. Secured to the arm 26 and insulated therefrom is a spring contact 37 bearing against the under side of the dial, which is of metal. Pivoted in a bracket 38 adjustable radially of the dial is a contact arm 39 overhanging the dial and as to its overhanging portion being beveled on the under side to an edge 40 (Fig. 14*) This contact arm has a nonconducting pivot 41 and is insulated from the bracket 38 by the non-conducting washers 42. When in the full line position in Fig. 14 it bears against an insulating pad 43. The contact arm 39 and contact piece 37 are the terminals of an electric circuit 44 including a battery 45 andan alarm device 46. I find it convenient to provide in the contact arm two holes 47, 48 in thelatter of which a pin 49 is placed when not in use and the former of which is employed as hereinafter stated.

The warper places in the holes 29 of the dial a peg 30 (as the one opposite the numeral 3) which is to serve to indicate that a predetermined number of yards for the section to be wound has been wound on the reel; at suitable intervals between this peg and O on the dial he places other pegs 30 in the holes, which are to serve to indicate when the lease cords are to be placed in the warp; finally in another hole a suitable distance from 0 and reading backward on the dial he places another peg, as the one near the numeral 11. It is assumed, of course, that when the winding on of a section is thus being prepared for, the dial (which may be removed from its bearingand replaced) is arranged wlth O opposite the pointer which the contact-arm 39 affords. When the winding on of'the section ensues, the clutch between the sprocket-wheel f and feed-screw 03 being established. and the carriage being therefore traversed through the medium of the feedscrew and nut 39, the feed-serew .through 21', 23, 21, 36, 35, and 32, drives the dial, which by reference'to the pointer 39 indicates by the numbers 1', 2, 3 etc. and the subdivisions the amount of yardage wound on. Asthe dial rotates the pegs 3O successively engage the arm 39'and-close the electric circuit to actuate the alarm 46, so that the operator is advised to stop the machine either to insert a lease cord or to sever the warp at the end of the section length predetermined, according as it is any one but the last or the last peg which thus closes the circuit. When the lastpeg closes the circuit and the machine is stopped and the predetermined length of warp is out 01f and properly secured to the reel the attendant disestablishes the clutch. and then'turns the handle 25 in a directionto reverse the rotation of the feed-screw and the dial. This results in feeding the carriage reversely to the direction in which it was automatically fed under the influence of the reel. The reversing operation is carried on not simply until 0 on the dial reaches the pointer (which means that the carriage is back to its previous starting point of traverse) but until the peg near the index 11 contacts with the pointer, whereupon the alarmwill again be sounded, this time indicating the position of the carriage for starting its traverse in the winding on of the next section. At this point it may be remarked that it is very essential, in order that the starting position of the carriage for the winding on of a new section shall be accurately determined, that the last-named peg be brought by the manual shifting of the carriage to its new position directly opposite the arm 39, for which purpose the pin 49 may be removed from the hole 48 and inserted in the hole 47' and in the space between the two teeth which are directly opposite the peg; some such expedient as this is necessary, else there might be a spacing between the section already wound on and the one next to be wound on which is greater than the distance between the threads in the warp, so that in the finished warp (composed of all the sections finally wound on the reel) there would result an undue space or break. The carriage being new positioned ready for the laying on of the new section of warp, the arm 39 is swung to the dotted line position in Fig. 14, the dial removed and replaced with 0 opposite the pointer and with its teeth in mesh with the worm 32, whereupon the pointer is returned to its full line position. Having established the clutch between f and d the winding on of a new section is ready to begin.

Clocks or indicators heretofore devised for warping machines have, so far as I am aware, been invariably operated from the shaft of the reel, whereby only the yardage wound on the reel may be determined. According to my invention, since the dial is in effect geared with the reed carriage, obtaining its motion from the intermediary part of the gearing which the feed-screw affords, it is possible not only to determine the extent of yardage wound on the reel but the extent of traverse of the carriage, and of the resetting traverse motion thereof, moreover, as well as of the working traverse motion thereof.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, a supporting structure, a reel journaled therein, a reed carriage arranged to traverse in said structure, indicating means including a movable indicating member, a rotary train operatively connecting said carriage and member and adapted to traverse the former and move the latter in synchrony with each other, and means to transmit motion from the reel to said train having a disconnective clutch connection.

2. In combination, with the frame, a reel journaled therein, a reed carriage arranged to traverse in the frame, a rotary feed-screw operatively engaged with and adapted to traverse the carriage, means to transmit motion from the reel to the feed-screw having a disconnective clutch connection, means to manually rotate the feed-screw, means to indicate the length of warp wound on the reel and the extent of traverse of the carriage including a moving member, and
